On the first point, I’ve never understood why it is important not to speak from notes when giving a presentation or making a speech. Ok, David Cameron can manage without notes (although, needed them yesterday in Parliament), but generally, referring to your notes is not unprofessional (although reading directly from them is). Public speaking is stressful enough without having to learn all your lines in advance. Rehearse, rehearse, rehearse and use minimal keyword notes you can understand.
On not looking as your slides, read the article Jerry Weissman. He says you need to look at your presentation slides, not as a reminder, but to encourage your audience to look at them too.
